accessing log files of one app for another app

A Web-app in my Organisation creates some log files, which are inside its WEB-INF directory. Can I make another app within the same container to access contents within another app's WEB-INF ?

The reason I ask this is because I am not allowed to add any filters to the original app but can use the log files for further analysis. While this is currently being done manually , I would like to automate it.
